An English map publisher who inherited the stock and business of Peter Stent. Overton was born in London, the son of Thomas Overton, a tailor in Covent Garden. He is believed to have been related to the bookseller, Henry Overton. With the foundation of the existing plate stock, Overton built Stent's business up to being the most successful in London by the end of the 17th Century. Overton was interested in maps, commissioning a range of interesting cartographic works including a world map, generally sold separately.
